The number of shares of Common Stock reserved and available for issuance under the ESPP is subject to an automatic annual increase on each January 1, beginning in 2021, by an amount equal to the least of: (i) one percent of the number of shares of Common Stock issued and outstanding on the immediately preceding December 31, (ii) 438,898 shares of Common Stock or (iii) such number of shares of Common Stock as determined by the Administrator (as defined in the ESPP). Accordingly, on January 1, 2021, the number of shares of Common Stock reserved and available for issuance under the ESPP increased by 438,898. The additional shares are of the same class as other securities relating to the Plan and the ESPP for which the Registrant’s registration statement filed on Form S-8 filed with the Securities and Exchange Commission on August 21, 2020 (File No. 333-248249), is effective.

Kymera Therapeutics, Inc.

200 Arsenal Yards Blvd., Suite 230

Watertown, MA 02472

We have acted as counsel to you in connection with your filing of a Registration Statement on Form S-8 (the “Registration Statement”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), on or about the date hereof relating to an aggregate of (i) 1,783,691 shares (the “Plan Shares”) of common stock, $0.0001 par value per share (the “Common Stock”), of Kymera Therapeutics, Inc., a Delaware corporation (the “Company”), that may be issued pursuant to the Kymera Therapeutics, Inc. 2020 Stock Option and Incentive Plan (the “Incentive Plan”) and (ii) 438,898 shares (the “ESPP Shares” and together with the Plan Shares, the “Shares”) of Common Stock of the Company that may be issued pursuant to the Amended and Restated Kymera Therapeutics, Inc. 2020 Employee Stock Purchase Plan (the “ESPP” and, together with the Incentive Plan, the “Plans”).

We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinion set forth below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinion set forth below, on certificates of officers of the Company.

The opinion set forth below is limited to the Delaware General Corporation Law.

For purposes of the opinion set forth below, we have assumed that no event occurs that causes the number of authorized shares of Common Stock available for issuance by the Company to be less than the number of then unissued Shares.

Based on the foregoing, we are of the opinion that the Shares have been duly authorized and, upon issuance and delivery against payment therefor in accordance with the terms of the Plans, will be validly issued, fully paid and nonassessable.

We hereby consent to the inclusion of this opinion as Exhibit 5.1 to the Registration Statement. In giving our consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.
